Vandals have smashed up federal Liberal leadership challenger Peter Dutton's electorate office and sprayed offensive comments about him on a nearby footpath.
The Brisbane office was extensively damaged after Mr Dutton this week mounted a challenge to topple prime minister Malcolm Turnbull.
Footage released by Queensland Police shows four people dressed in track pants, hooded jumpers and with their faces covered throwing brick pavers at the office about 1.45am on Friday.
Four reinforced glass windows, two glass doors and walls were extensively damaged.
A nearby footpath was also defaced with the words: "Deport Dutton" along with an obscene comment.
